Abstract

Using household data from surveys made in Sri Lanka, we provide original results regarding i) factors driving the perception of risk related to water consumption and ii) the role of perceived risk on household’s decision to treat water before drinking it. First, we find evidence that water aesthetic attributes (taste, smell, and color), household’s education and information about hygiene practices drive household’s assessment of safety risk. Second, we show that a higher perceived risk increases the probability that households boil or filter water before drinking it.
